DELIC
PEB 20571
Functional Description
4.11
DSP Core OAK+
The DELIC integrates an OAK+ DSP core, an enhanced version of the OAK. It is clocked
using an on-chip PLL at a frequency of 61.44 MHz. It may also be driven by lower clock
rates provided by an external oscillator.
The OAK+ is a high performance fixed-point DSP with a 16-bit data and program bus.
Due to an optimized cost-performance rate, it is widely used not only in Line Cards and
PBX applications, but also in cellular phones, fast modems, advanced fax machines, and
answering machines.
The core’s main block is a high performance central processing unit, including a full-
featured bit manipulation unit, RAM and ROM addressing units, and Program control
logic. All other application specific peripheral blocks, are defined as part of the user on-
chip logic.
The OAK+ provides an advanced set of DSP and generic microprocessor functions for
straightforward generation of efficient and compact code.
For more details on OAK architecture please refer to “DOC DSP Programmer’s
Reference Manual, 11.97”.
